Epiphyte, semi-epiphyte and terrestrial orchids
The different components of the mixture were chosen to meet the needs of both epiphytic and semi-epiphytic species. Orchid roots require both good ventilation and moisture, because they absorb the water and substances necessary to survive via aerial roots. This is precisely why Orchidee potting soil was formulated using pine bark and coir fibre. These materials give the potting soil excellent porosity and drainage for the growth of all types of orchids, while providing a sufficient supply of water and nutrition.
